The ADCMP600, ADCMP601, and ADCMP602 are very fast comparators fabricated on Analog Devices' proprietary XFCB2 process. These comparators are exceptionally versatile and easy to use. Features include an input range from VEE - 0.5 V to VCC + 0.5 V, low noise TTL-/CMOS-compatible output drivers, and latch inputs with adjustable hysteresis and/or shutdown inputs. The devices offer 3 ns propagation delay with 5 mV overdrive on 4 mA typical supply current. A flexible power supply scheme allows the devices to operate with a single +2.5 V positive supply and a -0.5 V to +3.0 V input signal range up to a +5.5 V positive supply with a -0.5 V to +6 V input signal range. Split input/output supplies with no sequencing restrictions on the ADCMP602 support a wide
